I see the photo of the 7 new NEX lenses for 2012. I am surprised and disappointed that there are no small or pancake lenses.

In the original photos of the Nex lens "roadmap" from Sony, the 30/3.5 looked pretty small. While it doesn't seem as small as the 16mm, it is smaller than the 18-55, and the size on-camera will be less than most of the adapted lenses, as Blue explains below.

As for the latest photo of the 30/3.5 where it looks larger, it looks kinda faked to me, so I'll wait before making final conclusions.
